An Inheritance And Linkage Study Of 19 Factor Pairs In Barley, Francis Cheney Lebaron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley, during the past three decades, has been used considerably for the study of linkage groups and character inheritance. The commercial varieties are diploids, having seven pairs of chromosomes. Six linkage groups have been established. According to studies on interchange by Kramer et al. (1954), two linkage groups, formerly designated as III and VII, may be separate arms of the same chromosome. They are now generally considered as one linkage group.

Though more than two hundred characters have been investigated, less than sixty have been assigned relative positions on genetic maps. In many cases, selection for good characters is …

Linkage And Inheritance Studies In Barley (Hordeum), Robert E. Heiner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley has had wide acceptance not only as a cultivated crop but also as an excellent source of genetic material. Barley was being used in inheritance studies by Tschermak when he rediscovered Mendel's laws of heredity. Since then barley has become one of the most widely used plants for genetic studies known today.

More than 100 characters have been investigated indicating the relative ease of classification. There are 7 linkage groups corresponding to the 7 chromosomes in which 2 or more characters have been located as reported by Robertson (1939). But Kramer, Veyl, and Hanson (1954), from translocation experiments, suggest …

Genetic Study Of Certain Spike And Floral Characters In Barley, Dwight Koonce

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to the commercial importance of barley many hybridization studies have been prosecuted in an effort to produce superior economic strains. While the economic breeding is still important, at present there is considerable scientific interest int he inheritance of the characters and in the location of the genes in the different linkage groups.

Bulletin No. 56 - Field Experiments With Wheat, Oats, And Barley, Lewis A. Merrill

UAES Bulletins

The testing of varieties is by no means the most important work of the Station. It, however, has its value in bringing into the State [Utah], and acclimating, new varieties that may be suited to our conditions better than any now grown. The results reached in these tests ought to receive the careful attention of our farmers, because success in raising cereals depends upon securing the varieties best suited to our purpose, and in growing those in greatest demand.

The experiments recorded in the following pages give the results of variety tests with wheat, oats and barley, and, in addition, …

Bulletin No. 34 - Relative Value Of Wheat, Peas, Corn And Barley In The Production Of Pork, A. A. Mills

UAES Bulletins

This bulletin treats of the use of wheat, peas, corn, and barley when mixed with bran and fed to pigs, the idea being to see if, by using one-half bran, the above grains could not be fed with profit, and also to test the relative value of the mixtures.
